Is it too late?

I feel like such a mess over what's been happening the past week. My boyfriend has decided he is unsure of our relationship and it's been messing with my head. Until now, I've just realized that this may be all my fault. He said he doesnt blame me but he needs to think things through and that I should be patient, which is killing me.

My behavior has been so toxic for him. I've been a clingy person and I always got mad whenever he took a long time to respond to a text. My sex drive is high and I would get upset when we went a week or more without it and always went straight to blaming him for not liking my body or seeing someone else. I have a bad temper and I always got upset easily and shut myself out by ignoring him until the next day.

His patience and affection was always there through all of this. I always appreciated it but I never thought of myself as a toxic person until I realized how bad my behavior has been. Last week he sprung this decision on me and it's been so painful watching us drift apart and barely talking anymore.

I do love him and I've always seen a future with him. Now I'm just hoping he will talk to me about what made him have this uncertainty and give me a chance to fix it. I'm so scared he will decide to break up and not tell me why. I told him I would like a chance to work this out once we've talked and he responded with "we'll see". Am I already too late to get a second chance? How can I convince him to stay before it's too late?
